The Moderated Mediating Effects of Nutrition and Physical Activity Between Fatigue and Quality of Life in Childhood Cancer Survivors

PURPOSE

The aim of this study was to investigate the associations between nutrition, physical activity, fatigue, and quality of life (QoL) among childhood cancer survivors. The specific purpose was to examine whether nutrition mediated and physical activity moderated the relationship between fatigue and QoL in this population.

METHODS

A pooled sample of 120 childhood cancer survivors was recruited at pediatric oncology wards and ambulatory settings between August 2020 and May 2021. We collected data on participants' demographic characteristics, fatigue, nutritional status, physical activity, and QoL. We then adapted Hayes Process Macro to examine the mediating and moderating effects of nutrition and physical activity on the relationship between fatigue and QoL.

RESULTS

In models adjusted for age and sex, (1) the simple mediation analysis identified the mediating effect of nutrition on the relationship between fatigue and QoL; and (2) the mediation and moderation analysis identified that the direct effect of nutrition between fatigue and QoL was significant when adding (a) physical activity and (b) fatigue × physical activity. There were significantly decreasing trends in physical activity at 1 standard deviation below the mean and at the mean, but not at 1 standard deviation above the mean.

CONCLUSIONS

Our findings demonstrate that nutrition mediated and physical activity moderated the relationship between fatigue and QoL. This highlights an opportunity to enhance QoL among childhood cancer survivors through healthy lifestyle interventions. To ensure that future interventions address children's needs and promote the greatest impact, such interventions should include nutrition and physical activity components that involve nurses, pediatric oncology physicians, nutritionists, and physical therapists.

Physical training interventions for children and teenagers affected by acute lymphoblastic leukemia and related treatment impairments

A decreased physical fitness has been reported in patients and survivors of acute lymphoblastic leukemia (ALL). This is influenced by the negative effects of the disease and by the treatments of childhood cancer.

In the past, children were advised to recover in bed, and to take as much relax as possible. Nowadays, it is considered that too much immobility may result in a further decrease of physical fitness and functioning. Exercise training for ALL children has frequently been reported to improve physical fitness and the well-being of the children, since it prevents the negative effects of a sedentary life-style, such as obesity and a poor skeletal health. In recent years, different studies and protocols on this subject has become available for children and young adults with cancer, both during and after treatment.

The efficacy of recent physical exercise training interventions, that act on several ALL impairments in children such as skeletal, musculoskeletal, neuromuscular, cardiopulmonary and cardiovascular systems, fatigue, body balance disorders and metabolism alterations have been examined.

These side effects might be prevented or significantly reduced by introducing a physical exercise program during or shortly after cancer treatment. Several interventions are discussed and presented for each impairment, reducing their level caused by the disease and thus suggesting the importance of physical training activity in ameliorating the children quality of life.

The Assessment of Fatigue in Children With Chronic Pain

The purpose of this study was to review the options that are available for assessing fatigue in children and adolescents with chronic pain problems, analyze the psychometric properties of all the instruments and provide health professionals with key information on which to base decisions about their use. A literature search was conducted using PsycINFO, MEDLINE, CINAHL, ERIC, and Scopus databases and the Cochrane Library between 1934 and January 2013 in order to identify all the studies that have evaluated fatigue in these populations. A total of 936 articles were retrieved, of which 24 were relevant. Of these 10 fatigue-related questionnaires were subject to specific content analysis. Only five of them evaluated fatigue in children with chronic pain, and just two had made a specific analysis of their psychometric characteristics. Most measures have been developed with a multidimensional approach of fatigue in mind. Psychometric information is missing for many questionnaires. On the basis of evidence-based assessment (EBA) criteria none of the questionnaires retrieved can be considered to be well-established measures that can be used in children with chronic pain.

Fatigue in child chronic health conditions: a systematic review of assessment instruments

BACKGROUND AND OBJECTIVE

Fatigue is common in chronic health conditions in childhood, associated with decreased quality of life and functioning, yet there are limited data to compare assessment instruments across conditions and childhood development. Our objective was to describe fatigue assessment instruments used in children with chronic health conditions and critically appraise the evidence for the measurement properties of identified instruments.

METHODS

Data sources included Medline, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO (using the EBSCOhost platform). Study selection included quantitative assessment of fatigue in children with health conditions. Data extraction was as follows: (1) study design, participant and fatigue instruments, (2) measurement properties of fatigue instruments, (3) methodological quality of included studies, and (4) synthesis of the quality of evidence across studies for the measurement properties of fatigue instruments.

RESULTS

Twenty fatigue assessment instruments were identified (12 child reports, 7 parent reports, 1 staff report), used in 89 studies. Fatigue was assessed in over 14 health conditions, most commonly in children with cancer and chronic fatigue syndrome. Evidence for the measurement properties of instruments varied, and overall quality was low. Two fatigue instruments demonstrated strong measurement properties for use in children with diverse health conditions and children with cancer.

CONCLUSIONS

The review is limited to children younger than 18 years and results are specific to health conditions described, limiting generalizability of findings to other populations. Evidence for the measurement properties of fatigue instruments varied according to the population in which instruments were used and informant. Further evidence is required for assessment of fatigue in younger children, and children with particular health conditions.

Measurement of fatigue in children and adolescents with cancer: an integrative review

This study analyzed scientific production on the measurement of fatigue in children and adolescents with cancer, particularly the instruments used. Integrative review, searching in PubMed, PsycINFO, Web of Science, CINAHL, LILACS, SciELO, IBECS and COCHRANE, without any time restriction, using key words and descriptors in different combinations. The review sample comprised 21 references. The results composed two categories: instrument development and validation and fatigue measurement. American nurses developed most studies, between 2002 and 2011, using two scales. The studies assessed the children and adolescents' self-reports and the parents' reports. They also associated fatigue with sleep pattern, quality of life, depression, survival and dexamethasone use. The importance of research on this theme is evidenced, including studies that apply these instruments in practice. The gap in knowledge production on this theme is highlighted in the Brazilian context.

Considering quality of life for children with cancer: a systematic review of patient-reported outcome measures and the development of a conceptual model

OBJECTIVES

An appraisal of pediatric cancer-specific quality-of-life (QOL) instruments revealed a lack of clarity about what constitutes QOL in this population. This study addresses this concern by identifying the concepts that underpin the construct of QOL as determined by a content analysis of all patient-reported outcome (PRO) instruments used in childhood cancer research.

METHODS

A systematic review was performed of key databases (i.e., MEDLINE, CINAHL, PsychINFO) to identify studies of QOL in children with cancer. A content analysis process was used to code and categorize all items from generic and cancer-specified PRO instruments. Our objective was to provide clarification regarding the conceptual underpinnings of these instruments, as well as to help inform the development of theory and contribute to building a conceptual framework of QOL for children with cancer.

RESULTS

A total of 6,013 English language articles were screened, identifying 148 studies. Ten generic and ten cancer-specific PRO instruments provided 957 items. Content analysis led to the identification of four major domains of QOL (physical, psychological, social, and general health), with 11 subdomains covering 98 different concepts. While all instruments reflected items relating to the broader domains of QOL, there was substantial heterogeneity in terms of the content and variability in the distribution of items.

CONCLUSIONS

This systematic review and the proposed model represent a useful starting point in the critical appraisal of the conceptual underpinnings of PRO instruments used in pediatric oncology and contribute to the need to place such tools under a critical, yet reflective and analytical lens.

Review of symptom experiences in children and adolescents with cancer

BACKGROUND

Inadequate symptom relief in children and adolescents with cancer leads to unnecessary suffering. This review assesses research on children and adolescents with cancer that had been published from 2002 to 2010.

OBJECTIVES

The review identifies the symptom experiences of children and adolescents undergoing treatment and describes the progress that has been made since Docherty's 2003 systematic review of nurse researcher published studies from 1990 to 2002, which identified gaps in research on the symptoms of pediatric oncology patients.

METHOD

A computerized search of medical and nursing literature produced 50 published studies and 2 dissertations that addressed the symptom experiences of children and adolescents receiving treatment for cancer.

RESULTS

Pain from cancer-related procedures and fatigue were the most frequently identified symptoms, followed closely by nausea and vomiting. More preschool-aged subjects and nonwhite subjects need to be assessed, distinctions between age groups and gender should be explored, and instrumentation for the prereading group must be developed.

CONCLUSIONS

Research on symptoms experienced by children and adolescents has gained momentum within the last 10 years, and some of the gaps identified by Docherty have been addressed. Multicenter trials would increase sample sizes and decrease enrollment time.

IMPLICATIONS FOR PRACTICE

By synthesizing research completed from 2002 to 2010 on symptoms of children who had cancer, new ideas can be generated and shared with clinical nursing staff to improve patient care. Gaps to further direct research are also identified.

Descriptive analysis of the verbal behavior of a therapist: a known-group validity analysis of the putative behavioral functions involved in clinical interaction

This study analyzes the interobserver agreement and hypothesis-based known-group validity of the Therapist's Verbal Behavior Category System (SISC-INTER). The SISC-INTER is a behavioral observation protocol comprised of a set of verbal categories representing putative behavioral functions of the in-session verbal behavior of a therapist (e.g., discriminative, reinforcing, punishing, and motivational operations). The complete therapeutic process of a clinical case of an individual with marital problems was recorded (10 sessions, 8 hours), and data were arranged in a temporal sequence using 10-min periods. Hypotheses based on the expected performance of the putative behavioral functions portrayed by the SISC-INTER codes across prevalent clinical activities (i.e., assessing, explaining, Socratic method, providing clinical guidance) were tested using autoregressive integrated moving average (ARIMA) models. Known-group validity analyses provided support to all hypotheses. The SISC-INTER may be a useful tool to describe therapist-client interaction in operant terms. The utility of reliable and valid protocols for the descriptive analysis of clinical practice in terms of verbal behavior is discussed.

Review Article: A Systematic Review of Cancer-Related Fatigue Measurement Questionnaires

Purpose: Cancer-related fatigue (CRF) is a common symptom experienced by patients in all stages and in cancer survivors. The main objectives of this review were to identify validated CRF instruments, and populations in whom these tools have been validated. Methods: We used a systematic review methodology. Three separate searches were performed using different MeSH terms in Pub Med and Ovid databases. Articles were analyzed for validation and reliability. Results: A total of 1453 papers from 3 different searches identified 40 instruments (3 unidimensional and 37 multidimensional). Instruments varied by psychometric properties, items, scale, dimension, cancer site, and population. Five were optimally tested for validity and reliability. Completion rates, sensitivity to change, and test—retest reliability were reported for a few. Discussion: Most tools had been validated in mixed populations and are relatively insensitive to differences in fatigue to cancer stage. Most instruments are burdensome for those with advanced cancer. The Brief Fatigue Inventory and 3 fatigue items of the European Organization for Research and Treatment Quality of Life Questionnaire Fatigue Scale (EORTC QLQ-C30) are optimal instruments in advanced cancer. Conclusions: In all, 40 CRF instruments were identified. Validity and reliability varied by questionnaire. The ideal item numbers, scale, and domains are not established and may be population dependent.

Clinical factors associated with fatigue over time in paediatric oncology patients receiving chemotherapy

The purpose of this study was to investigate the relationships between clinical factors (including haemoglobin value, chemotherapeutic agents, and corticosteroid use) and changing patterns of fatigue before and for the next 10 days following the start of a new round of chemotherapy in children with cancer. A prospective longitudinal design was used to collect data from 48 paediatric oncology patients who were about to begin a new round of chemotherapy and their parents. Fatigue levels were assessed using multidomain questionnaires with three categories of patient self-report (including 'General Fatigue', 'Sleep/Rest Fatigue', and 'Cognitive Fatigue') and four categories of parent proxy-report (including 'Lack of Energy', 'Unable to Function', 'Altered Sleep', and 'Altered Mood'). The findings suggest that fatigue from both patient self-report and parent proxy-report changed significantly over time. The major findings from this study are that patients have more problems with fatigue in the first few days after the start of a cycle of chemotherapy. Corticosteroid use and haemoglobin value were associated with significant increases in fatigue that were sustained for several days and reached the highest level of fatigue at day 5 for those receiving concurrent steroids. The association of chemotherapeutic agents with fatigue varied between patient self-report and parent report, but the type of chemotherapeutic agents used was not associated with most changes in fatigue.
